Application July 5, 1944, Serial No. 3,578

The present invention relates to the cleaning and humidiiying of the suction air of an internal combustion engine, and also to the intimate admixing and atomization of the air and entrained form as possible and in a high degree of atomization, and (c) that the admixture be effected by the suction action whereby air is sucked into the engine during the suction strokes thereof.

A primary object of the present invention is the provision of a cleaning and humidifying construction which shall effect an efilcient realization of the above-enumerated desiderata.

To this end, briefly stated, the present invention provides a novel relationship of parts wherein the suction air is first passed through a filter which eliminates dust and other undesired foreign matter therefrom, and is then passed over the moist surface of the outer wall of a porous water reservoir before being passed through a porous cylindrical passageway extending through said reservoir, whereby the desired cleaning and atomization are effected. The said passageway preferablyassumes the form of a Venturi nozzle whereby enhanced humidification, admixture of air and moisture, and atomization of the mixture are realized.

A presently-preferred mode of carrying out the invention is shown diagrammatically, by way ofexample, on the accompanying sheet of drawing, the single figure of which represents a sectional view through the center .of the device.

As shown on the said figure of drawing, the cleaner and humidifier according to this invention may comprise a water-reservoir which is generally U-shaped in cross section and which comprises an inner essentially cylindrical wall i0, an outer essentially cylindrical wall I I and a bottom |2. These parts, which are preferaby integral, as

The reservoir may be filled by way of a filler tube l3 provided on the metallic disk-like cover I. The latter is provided with a central opening in substantial alinement with the central passage way defined by the inner wall I0. Flanges i5 are provided on cover I4 to assist in retaining the 1 Claim. (Cl. 261-99) same in proper position on the walls It, l l. The stem of the level-indicating float it passes through tube i1 afilxed to the top of the cover ll, as shown.

The reservoir is preferably seated in an 'upwardly peripherally flanged metallic base l8 which is also provided with a central opening in substantial alinement with the aforesaid central passageway. Means in the form of a fiange member 19, suitably secured to the bottom of base l8, and a clamp and clamp-bolt assembly 20, are provided for associating the cleaner and humidifier assembly with a conduit leading to the intake side of the carburetor.

surmounted on the reservoir and in spaced relation thereto, as shown, is the encasing jacket 2|, made or metal or the like. Jacket 2| preterably snaps onto the reservoir with the aid of a plurality oi spring tabs 22 or the like, some of which bear resiliently against the cover I and others of which bear resiliently against the base It, as shown. A suitable number of spring tabs 22 arranged in spaced relationship peripherally oi the jacket 2| is provided.

The jacket 2| terminates in a peripherally extending bottom 23 provided with an upstanding flange 24 defining aspacefor the reception of a filter element. This may comprise a metallic cylindrical wall 2! of inverted L-shape in cross section, encasing filter-forming material such as copper filings; glass wool or the like. The wall of jacket 2| is foraminous adjacent the filter element, as shown at 28.

The level indicator l8 and filter tube i3 extend through corresponding openings in the jacket 2L.

Thereservoir may be arranged anteriorly or posteriorly of the carbureter or in front of the suction openingoi the engine. Air sucked in during the suction stroke of the internal combustion engine with which the device is associated, passes through the filter element and is cleaned of its foreign ingredients. The air then II and jacket 2| whereby an initial humidification of the air, combined with a further "cleaning action, takes place with the aid of water seeping through to the exterior of the said wall. The air then passes over to and downwardly through the central passage defined by the nozzle-shaped inner wall I0 and entrains from the surface of the latter the' requisite quantity of moisture. The

greater the suction action on the airpassing through the said central passage, the greater the velocity thereof and the greater the amount of water entrained from the surface oi the wall Ill.

a that, during the suction stroke 01' the engine, not

only is an increased quantity of moisture entrained by the air per unit of area of porous nozimproved admixture with the moisture' comins throughs'aid inner wall, a jacket 'encompassins zle material, .as compared with a truly cylindrical to the jet effect also results in a better mixing of the sucked-in air and entrained waterpar ticles and also a better atomization of the resultant mixture. I i

It is evident from the foregoing'that therelationship of parts according to the present invention realizes the objects of the invention as above set forth.

' central passage,bu't the increased velocity due It is to be understood'that the specific em bodiment above described in detail is purely exemplary in character and that the invention is not to be limited except as required by the terms of the claim hereunto appended.

Having thus disclosed the invention, what is claimed is: v

A humidifier for the carburetor of an internal combustion engine comprising a support, an annular water reservoir on said support having an inner wall and an outer wall of porous material so that water in said reservoir may seep therethrough, said inner wall defining a substantially central unobstructed passageway through said reservoir] and being of Venturi configuration whereby an enhainced suction action may be said reservoir and support, a fixed clamp structure on said Jacket to support the jacket on the upper end of said reservoir and a movable clamp structureto contact the under side or said support at the lower end of said reservoir, said jacket being spaced from said outer wall to define a peripheral passageway having communication with said central passageway and said jacket being provided with air inlet means leading into the bottom of said peripheral passageway whereby air drawn into the latter is subjected to the humidifying action of moisture seeping through said outer wall before; being drawn into said centralpassageway.
